Design
Neotherm is an oil-fired thermic fluid heater of vertical design. It has four heat-transfer passes for optimum efficiency.
Packaged models
Supplied as a packaged unit, so erection takes very little time and site work is minimal. Only power, oil, water and chimney connections are needed to start up.
Fully automatic
Neotherm switches ON and OFF automatically against the temperature set on the temperature controller. A specially trained attendant doesn't need to watch it continuously.
Record efficiency
Efficient combustion, forced circulation, generous heat-transfer areas and a large furnace volume give an overall efficiency of 88 % on NCV of oil.
Applications
Chemical reactorsDyeing & stentersCorrugationRubber & tyreEdible oil & foodHot-melt & bitumen
